any films spring to mind where it ended DIFFERENTLY to what you expected?

just seen mission impossible 3 and it ended pretty much exactly as I expected and kind of ruined the film.
(the missus whispering, just die...please just die...) didn't help the predictability factor!

only ones I can think of that took me a bit of a surprise are the original italian job and seven also suppose fight club was quite surprising! lol

anyone any good twist films?
